You know what, yes. But to be honest...My whole car is freakin' loud. I have a full Stainless system with a high flow cat section and it isn't for the faint of ear . But yes, I remember back when I had only intake sound and a quieter exhaust. BrianI have noticed a power difference. Bheinz, does your car start to get much louder when you hit 4000 rpm, or when you put the pedal to the ground?
